In the course of UNICEF’s work during the past decade, the child-friendly school (CFS) model has emerged as the organization’s signature means to advocate for and promote quality education for every girl and boy. The model can be viewed as a package solution and a holistic instrument for pulling together a comprehensive range of interventions in quality education. As the main proponent of this model, UNICEF has developed the manual as a reference document and practical guidebook to help countries implement CFS.
